Arkansas and Kansas derive from similar roots. The Algonquin name for the Quapaw tribe was acansa. The Algonquin name for the related Kaw tribe was kansa.
It was not until 1881 that it was settled that Arkansas would be pronounced AR-ken-SAW rather than Ar-KAN-ses.
In Kansas, the Arkansas River is known as the Ar-KAN-ses River. There is a Kansas River--sometimes called the Kaw River--in northeastern Kansas. It flows into the Missouri River where Kansas City--named for the river--is today.
